4 .2 Use of single-line receivers
The MICROBEAST enables the use of conventional receivers with individual channel outputs or the use of
special receivers which output the channel signals as a merged single-line signal. These include Spek trum®
satellite receivers, PPM composite signal receiver (e.g. Futaba® SP Series receiver or the satellite receiver from
Jeti ®), receivers with Futaba® S-BUS as well as receivers with SRXL compatible data output (e.g. SRXL-
Multiplex or BEASTRX).
4 .2 .1 General notes
When operating with single-line receivers (Spektrum® satellite receiver, PPM composite signal receiver
- e.g. Futaba® SP-series or the satellite receiver from Jeti®, receivers using Futaba® S-BUS, SRXL
compatible receivers), the throttle servo/motor controller can be connected to [CH5] on the
MICROBEAST. When using a motor controller for electric models with a BEC this slot then also will be
supplying the MICROBEAST, the servos and the receiver with power.
We recommend if possible (e.g. on all receivers that have normal servo connectors together with single
line output) to connect the throttle servo/motor controller directly to the receiver to benefit from the
native Failsafe/Hold functions. Although the MICROBEAST also has adjustable Failsafe for [CH5] this will
only be activated when the connection between MICROBEAST unit and receiver fails but not for
example in case of signal loss between transmitter and receiver.
On slot [DI2 | CH7 | CH6] another auxiliary channel is available on the top pin [CH6] , for example to
hook up a governor for nitro engines. Please note that this slot is only issuing a control signal and has
no power. For this reason a servo cannot be plugged here directly. The two lower pins [DI2] and [CH7]
are reserved for other applications. Never connect a power source on those two pins: this could
damage the MICRObeAST!
In the case of an electric model if the ESC has a second BEC output or when using a buffering battery
this wire can be connected to the [SYS] terminal or (if possible) plugged directly into the receiver.
On models with a separate power supply this can only be connected to the MICROBEAST on slot [SYS].
Therefore please ensure adequate sizing of the supply lines, especially with large models. A second
power connection can be derived to the receiver or, by using a Y cable, you can inject a parallel power
supply to one of the servo outputs. When using very powerful servos you might even consider using a
separate voltage regulating unit that the servos can be connected to.
